Luring is guiding a dog into a position. You have to get rid of the lure after about 6-12 trials so it does not become a bribe. A bribe is when your dog only does something if he can see a treat or his reward. A reward is something that the dog gets for doing something right or just for being awesome. A bribe is presented before the dog does something, a reward is given after a desired behavior. To avoid bribing your dog, practice commands without showing him treats or rewards. After the dog does something, go and get the reward or pet him and love on him.
